Implementations of Pablock Suite smazrt contracts, includes:

• PablockToken: ERC20 Utility Token to use Pablock services.
• PablockNFT: ERC721 token to generate custom NFT
• PablockNotarization: Notarization contract to save file hash on blockchain
• PablockMultiSign: Facotry to deploy multi sign contract.
• EIP712 compatible meta transaction.

npm install git+https://github.com/bcode-tech/Pablock-Smart-Contracts

or

yarn add git+https://github.com/bcode-tech/Pablock-Smart-Contracts

Trying to improve the contracts? Test? Deploy? Run scripts?

Use a .env file based on .env.example to store private keys and other variables, if you plan to deploy or test outside the local environment.

For testing meta transaction the test will need private keys of hardhat generated wallet. Run:

npx hardhat node

Take a bunch of keys and store them in privateKeys.json as an array, the keys will not need of 0x prefix.

Install all the dependencies:

yarn install

Run all test:

npx hardhat test

Run specific test:

npx hardhat test test/PablockNotarization.test.ts

Deploy:

npx hardhat run scripts/deploy.ts --network <network_name>

Once installed, use PablockMetaTranasactionReceiver to enable Pablock meta transaction on your contract.

pragma solidity 0.8.9;
import "pablock-smart-contract/contract/PablockMetaTxReceiver.sol";

contract MyContract is PablockMetaTxReceiver {
  constructor(address metaTxAddress)
    PablockMetaTxReceiver("MyContract", "0.0.1")
  {
    setMetaTransaction(metaTxAddress);
  }
}

metaTxAddress rappresents the deployment address of EIP712MetaTransaction deployed by BCode from the Pablock ecosystem.
